Description Matteo Castellini 2012-05-31 08:43:35 EDT
Description of problem:
Under Fedora 17 I cannot use keyboard and mouse connected to the KVM switch  StarTech SV431DDVDUA. I was able to use it without any problem under Fedora 16

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Boot the computer
2. Connect the KVM switch
3. Try using either keyboard or mouse connected to the KVM switch
Actual results:
No response from keyboard (nothing happens even tapping Caps lock) or mouse

Expected results:
keyboard and mouse work properly

Additional info:
I attached directly to the computer keyboard and mouse are working without any problem

I can also confirm this bug.  I reinstalled F16 to check the KVM still worked and it's fine.  F17 does not recognise the keyboard or mouse.  They work fine if plugged directly into the machine.

They also don't work during the Anaconda install/upgrade process from the DVD.  However it does seem as though they are recognised by the Plymouth splash screen as hitting escape shows the textual progress.

dmesg doesn't show anything obvious.  Sensible looking things like this show:

The problem is present on xorg-x11-server-Xorg-1.12.2-1.fc17.x86_64 as well. Any pointers / directions on how to provide any meaningful informations for debugging?
Comment 3 Andy Sturrock 2012-06-22 11:24:56 EDT
I just did a "yum -y update" followed by a reboot and the problem seems to be fixed.
Comment 4 Matteo Castellini 2012-06-25 04:07:07 EDT
Fixed for me too, looks like something in the last updates fixed it. Closing it as this bug report is not needed anymore.
